ICD-10 Code L98.416 – Non-pressure chronic ulcer of buttock with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.416 – Non-pressure chronic ulcer of buttock with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer located on the buttock that extends to the bone, with no documented necrosis. Use it when the record clearly shows bone involvement and the ulcer is not a pressure injury.
Clinical signs
Typical documentation may describe a persistent open wound on the buttock with exposed or involved bone. Clinical features vary; refer to documentation, and confirm that necrosis is not present.
When to use this code
Use L98.416 when the provider documents a chronic non-pressure ulcer of the buttock and specifies bone involvement. It applies when the site is the buttock and the ulcer is not coded as a pressure ulcer. If laterality or depth details are unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with documented necrosis. If the wound location is different or the record is incomplete, check documentation.
Coding tip
Verify both the anatomic site and the depth statement; “bone involvement” must be explicitly documented for this code.
